The chestnut-tipped toucanet (Aulacorhynchus derbianus) is a near-passerine bird in the toucan family Ramphastidae. It is found in Bolivia, Colombia, Ecuador, and Peru. The chestnut-tipped toucanet is monotypic. However, what is now the tepui toucanet (A. whitelianus) and it were for a time considered conspecific. They were separated by major taxonomic systems beginning in 2011. The chestnut-tipped and groove-billed toucanets (A. sulcatus) form a superspecies.
The chestnut-tipped toucanet is 33 to 41 cm (13 to 16 in) long and weighs 141 to 262 g (5.0 to 9.2 oz). Its bill is deep red and black with a vertical white line at its base and grooves on the maxilla. (Some individuals have an all-black bill). The sexes are alike. Their plumage is generally green, with a bluish nape, a white throat, and wide chestnut tips on the tail feathers. The red-brown eye has some blue below it.
The chestnut-tipped toucanet is found along the east slope of the Andes from extreme southern Colombia through Ecuador and Peru into western Bolivia as far as Cochabamba Department. It primarily inhabits subtropical montane cloudforest... Wikipedia →

Rare
Under 5% of wildlife watchers report a Chestnut-tipped Toucanet sighting in Podocarpus National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 360th most-seen of the 446 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Chestnut-tipped Toucanet in Podocarpus National Park on a given day, so our monthly data shows no clear season.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Chestnut-tipped Toucanet sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 parks where we can rate Chestnut-tipped Toucanet sightings, Podocarpus National Park ranks 2nd at under 5%. The best odds are in Amboró National Park (Bolivia, about 10%).
GBIF citizen-science records
It is estimated from how often the Chestnut-tipped Toucanet is recorded against all the birds logged in Podocarpus National Park (11 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
